Manufactured in the UK by C-TEC, the C4403B is a \u003cstrong\u003eType B fixed-temperature heat detector\u003c\/strong\u003e that activates when temperatures reach the specified alarm threshold, making it well suited to environments where heat detection is preferred over smoke detection. It is \u003cstrong\u003ethird-party certified to EN54-5 by Intertek\u003c\/strong\u003e, providing assurance of its compliance with recognised fire detection standards. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe C4403B offers reliable operation across a wide \u003cstrong\u003e9–33V DC operating range\u003c\/strong\u003e and features two ultra-bright red LED indicator strips providing \u003cstrong\u003e360° visibility\u003c\/strong\u003e of an alarm condition. Its conventional two-wire, polarity-sensitive design makes it compatible with virtually all known conventional fire alarm panels, including C-TEC's CFP, FP, MFP and EP203 ranges, subject to system requirements. The detector is also compatible with C-TEC ActiV \u003cstrong\u003eC4408, C4408D and C4408R series bases\u003c\/strong\u003e, providing flexibility when specifying a complete conventional fire alarm system. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eDesigned with practicality and durability in mind, the \u003cstrong\u003eC-TEC ActiV C4403B heat detector\u003c\/strong\u003e features a white polycarbonate housing and a compact design measuring approximately \u003cstrong\u003e102.2mm in diameter\u003c\/strong\u003e.
